The objective of this study was to assess the accuracy and safety of two pre-defined checklists to identify prehospital post-ictal or hypoglycemic patients who could be discharged at the scene.
Methods
A retrospective cohort study of lower acuity, adult patients attended by paramedics in 2013, and who were either post-ictal or hypoglycemic, was conducted. Two self-care pathway assessment checklists (one each for post-ictal and hypoglycemia) designed as clinical decision tools for paramedics to identify patients suitable for discharge at the scene were used. The intention of the checklists was to provide paramedics with justification to not transport a patient if all checklist criteria were met. Actual patient destination (emergency department [ED] or discharge at the scene) and subsequent events (eg, ambulance requests) were compared between patients who did and did not fulfill the checklists. The performance of the checklists against the destination determined by paramedics was also assessed.
Results
Totals of 629 post-ictal and 609 hypoglycemic patients were identified. Of these, 91 (14.5%) and 37 (6.1%) patients fulfilled the respective checklist. Among those who fulfilled the checklist, 25 (27.5%) post-ictal and 18 (48.6%) hypoglycemic patients were discharged at the scene, and 21 (23.1%) and seven (18.9%) were admitted to hospital after ED assessment. Amongst post-ictal patients, those fulfilling the checklist had more subsequent ambulance requests (P=.01) and ED attendances with seizure-related conditions (P=.04) within three days than those who did not. Amongst hypoglycemic patients, there were no significant differences in subsequent events between those who did and did not meet the criteria. Paramedics discharged five times more hypoglycemic patients at the scene than the checklist predicted with no significant differences in the rate of subsequent events. Four deaths (0.66%) occurred within seven days in the hypoglycemic cohort, and none of them were attributed directly to hypoglycemia.
Conclusions
The checklists did not accurately identify patients suitable for discharge at the scene within the Emergency Medical Service. Patients who fulfilled the post-ictal checklist made more subsequent health care service requests within three days than those who did not. Both checklists showed similar occurrence of subsequent events to paramedics’ decision, but the hypoglycemia checklist identified fewer patients who could be discharged at the scene than paramedics actually discharged. Reliance on these checklists may increase transportations to ED and delay initiation of appropriate treatment at a hospital.

There is a cascade of risks associated with a hazard evolving into a disaster that consists of the risk that: (1) a hazard will produce an event; (2) an event will cause structural damage; (3) structural damage will create functional damages and needs; (4) needs will create an emergency (require use of the local response capacity); and (5) the needs will overwhelm the local response capacity and result in a disaster (ie, the need for outside assistance). Each step along the continuum/cascade can be characterized by its probability of occurrence and the probability of possible consequences of its occurrence, and each risk is dependent upon the preceding occurrence in the progression from a hazard to a disaster. Risk-reduction measures are interventions (actions) that can be implemented to: (1) decrease the risk that a hazard will manifest as an event; (2) decrease the amounts of structural and functional damages that will result from the event; and/or (3) increase the ability to cope with the damage and respond to the needs that result from an event. Capacity building increases the level of resilience by augmenting the absorbing and/or buffering and/or response capacities of a community-at-risk. Risks for some hazards vary by the context in which they exist and by the Societal System(s) involved.

The aim of disaster reduction education (DRE) is to achieve behavioral change. Over the past two decades, many efforts have been directed towards this goal, but educational activities have been developed based on unverified assumptions. Further, the literature has not identified any significant change towards disaster preparedness at the individual level. In addition, previous research suggests that change is dependent on multiple independent predictors. It is difficult to determine what specific actions DRE might result in; therefore, the preamble of such an action, which is to have discussions about it, has been chosen as the surrogate outcome measure for DRE success. This study describes the relationship of the perceived entity responsible for disaster education, disaster education per se, sex, and country-specific characteristics, with students discussing disasters with friends and family as a measure of proactive behavioral change in disaster preparedness.
Methods
A total of 3,829 final year high school students participated in an international, multi-center prospective, cross-sectional study using a validated questionnaire. Nine countries with different levels of disaster exposure risk and economic development were surveyed. Regression analyses examined the relationship between the likelihood of discussing disasters with friends and family (dependent variable) and a series of independent variables.
Results
There was no statistically significant relationship between a single entity responsible for disaster education and discussions about potential hazards and risks with friends and/or family. While several independent predictors showed a significant main effect, DRE through school lessons in interaction with Family & Charity Organizations had the highest predictive value.
Conclusions
Disaster reduction education might require different delivery channels and methods and should engage with the entities with which the teenagers are more likely to collaborate.

Crush syndrome, of which little is known, occurs as a result of compression injury to the muscles. This syndrome is characterized by systemic manifestations such as acute kidney injury (AKI), hypovolemic shock, and hydroelectrolytic variations. This pathology presents high morbidity and mortality if not managed aggressively by prehospital care.
Clinical Case
A 40-year-old worker was rescued after being buried underground in a ditch for 19 hours. The patient was administered early resuscitation with isotonic solutions and monitored during the entire rescue operation. Despite having increased plasma levels of total creatine kinase (CK), the patient did not develop AKI or hydroelectrolytic variations.
Conclusion
Aggressive early management with isotonic solutions before hospital arrival is an effective option for nephron-protection and prevention of crush syndrome.

The maritime environment presents a unique set of challenges to search and recovery (SAR) operations. There is a paucity of information available to guide provision of medical support for SAR operations for aircraft disasters at sea. The Republic of Singapore Navy (RSN) took part in two such SAR operations in 2014 which showcased the value of a military organization in these operations. Key considerations in medical support for similar operations include the resultant casualty profile and challenges specific to the maritime environment, such as large distances of area of operations from land, variable sea states, and space limitations. Medical support planning can be approached using well-established disaster management life cycle phases of preparedness, mitigation, response, and recovery, which all are described in detail. This includes key areas of dedicated training and exercises, force protection, availability of air assets and chamber support, psychological care, and the forensic handling of human remains. Relevant lessons learned by RSN from the Air Asia QZ8501 search operation are also included in the description of these key areas.

The 11th of March 2011, a magnitude 9.0 earthquake struck alongside the north-east coast of Honshu Island, Japan, causing a tsunami and a major nuclear accident. The French Institute for Public Health Surveillance (InVS) set up, within one week after the triple catastrophe, an Internet-based registry for French nationals who were in Japan at the time of the disasters. In this string of disasters, in this context of uncertainties about the nuclear risks, the aim of this registry was to facilitate the: (1) realization of further epidemiologic studies, if needed; and (2) contact of people if a medical follow-up was needed. The purpose of this report was to describe how the health registry was set up, what it was used for, and to discuss further utilization and improvements to health registries after disasters.
Methods
The conception of the questionnaire to register French nationals was based on a form developed as part of the Steering Committee for the management of the post-accident phase in the event of nuclear accident or a radiological emergency situation (CODIRPA) work. The questionnaire was available online.
Results
The main objective was achieved since it was theoretically possible to contact again the 1,089 persons who completed the form. According to the data collected on their space-time budget, to the result of internal contamination measured by the French Institute for Radiological Protection and Nuclear Safety (IRSN) and dosimetric expertise published by the World Health Organization (WHO), it was not suitable to conduct an epidemiologic follow-up of adverse effects of exposure to ionizing radiations among them. However, this registry was used to launch a qualitative study on exposure to stress and psychosocial impact of the Great East Japan Earthquake on French nationals who were in Japan in March 2011.
Conclusion
Setting a registry after a disaster is a very important step in managing the various consequences of a disaster. This experience showed that it is quickly feasible and does not raise adverse side effects in involved people.

Inter-facility transport of critically ill patients is associated with a high risk of adverse events, and critical care transport (CCT) teams may spend considerable time at sending institutions preparing patients for transport. The effect of mode of transport and distance to be traveled on on-scene times (OSTs) has not been well-described.
Problem
Quantification of the time required to package patients and complete CCTs based on mode of transport and distance between facilities is important for hospitals and CCT teams to allocate resources effectively.
Methods
This is a retrospective review of OSTs and transport times for patients with hypoxemic respiratory failure transported from October 2009 through December 2012 from sending hospitals to three tertiary care hospitals. Differences among the OSTs and transport times based on the mode of transport (ground, rotor wing, or fixed wing), distance traveled, and intra-hospital pick-up location (emergency department [ED] vs intensive care unit [ICU]) were assessed. Correlations between OSTs and transport times were performed based on mode of transport and distance traveled.
Results
Two hundred thirty-nine charts were identified for review. Mean OST was 42.2 (SD=18.8) minutes, and mean transport time was 35.7 (SD=19.5) minutes. On-scene time was greater than en route time for 147 patients and greater than total trip time for 91. Mean transport distance was 42.2 (SD=35.1) miles. There were no differences in the OST based on mode of transport; however, total transport time was significantly shorter for rotor versus ground, (39.9 [SD=19.9] minutes vs 54.2 [SD=24.7] minutes; P <.001) and for rotor versus fixed wing (84.3 [SD=34.2] minutes; P=0.02). On-scene time in the ED was significantly shorter than the ICU (33.5 [SD=15.7] minutes vs 45.2 [SD=18.8] minutes; P <.001). For all patients, regardless of mode of transportation, there was no correlation between OST and total miles travelled; although, there was a significant correlation between the time en route and distance, as well as total trip time and distance.
Conclusions
In this cohort of critically ill patients with hypoxemic respiratory failure, OST was over 40 minutes and was often longer than the total trip time. On-scene time did not correlate with mode of transport or distance traveled. These data can assist in planning inter-facility transports for both the sending and receiving hospitals, as well as CCT services.

The Great East Japan Earthquake of March 11, 2011 may have influenced the long-term health of those in the disaster area. It is important to collect current and future health information of the people living in the post-disaster area to provide appropriate health support and quality-oriented care. However, public perceptions of health and genomic studies in the Great East Japan Earthquake disaster area are still unknown.
Methods
A questionnaire survey was conducted in one town affected by the Great East Japan Earthquake and subsequent tsunami. The results of the questionnaire were tailed and the differences in responses to each question were assessed by sex and age.
Results
In 284 eligible people (137 men, 147 women), almost all participants agreed to join a health survey investigating the adverse effects of the disaster, and over 80% of the total participants agreed to genomic analysis. Over 70% of the participants wanted to receive pharmacogenetic testing and to receive feedback on which medications were suitable or unsuitable for them.
Conclusions
Most people living in the disaster area are interested in health surveys. Most of the participants also showed interest in genomic analysis.

On-scene time (OST) previously has been shown to be a significant component of Emergency Medical Services’ (EMS’) operational delay in acute stroke. Since stroke patients are managed routinely by two-person ambulance crews, increasing the number of personnel available on the scene is a possible method to improve their performance.
Hypothesis
Using fire engine crews to support ambulances on the scene in acute stroke is hypothesized to be associated with a shorter OST.
Methods
All patients transported to hospital as thrombolysis candidates during a one-year study period were registered by the ambulance crews using a case report form that included patient characteristics and operational EMS data.
Results
Seventy-seven patients (41 [53%] male; mean age of 68.9 years [SD=15]; mean Glasgow Coma Score [GCS] of 15 points [IQR=14-15]) were eligible for the study. Forty-five cases were managed by ambulance and fire engine crews together and 32 by the ambulance crews alone. The median ambulance response time was seven minutes (IQR=5-10) and the fire engine response time was six minutes (IQR=5-8). The number of EMS personnel on the scene was six (IQR=5-7) and two (IQR=2-2), and the OST was 21 minutes (IQR=18-26) and 24 minutes (IQR=20-32; P =.073) for the groups, respectively. In a following regression analysis, using stroke as the dispatch code was the only variable associated with short (<22 minutes) OST with an odds ratio of 3.952 (95% CI, 1.279-12.207).
Conclusion
Dispatching fire engine crews to support ambulances in acute stroke care was not associated with a shorter on-scene stay when compared to standard management by two-person ambulance crews alone. Using stroke as the dispatch code was the only variable that was associated independently with a short OST.

The authors report the results of surveys on the emergency transport or evacuation status of obstetric patients conducted in Miyagi prefecture, one of the major disaster areas of the Great East Japan Earthquake and tsunami.
Methods
The surveys examined the damages to maternity institutions, evacuation status and transport of pregnant women, and prehospital childbirths and were conducted in 50 maternity institutions and 12 fire departments in Miyagi.
Results
Two coastal institutions were destroyed completely, and four institutions were destroyed partially by the tsunami, forcing them to stop medical services. In the two-month period after the disaster, 217 pregnant women received hospital transport or gave birth after evacuation. Satisfactory perinatal outcomes were maintained. Emergency obstetric transport increased to approximately 1.4 fold the number before the disaster. Twenty-three women had prehospital childbirths, indicating a marked increase to approximately three times the number of the previous year.
Conclusion
In the acute phase of the tsunami disaster, maternity institutions were damaged severely and perinatal transport was not possible; as a result, pregnant women inevitably gave birth in unplanned institutions, and the number of prehospital births was increased extremely. To obtain satisfactory obstetric outcomes, it is necessary to construct a future disaster management system and to re-recognize pregnant women as people with special needs in disaster situations.

With the increase in natural and manmade disasters, preparedness remains a vital area of concern. Despite attempts by government and non-government agencies to stress the importance of preparedness, national levels of preparedness remain unacceptably low. A goal of commands and installations is to ensure that US Navy beneficiaries are well prepared for disasters. This especially is critical in active service members to meet mission readiness requirements in crisis settings.
Objective
To evaluate active duty Navy personnel, dependents, veterans, and retirees regarding disaster preparedness status.
Methods
The authors conducted an anonymous 29-question survey for US Navy active duty, dependents, veterans, and retirees of the Greater San Diego Region (California, USA) evaluating actual basic disaster readiness as determined by the Federal Emergency Management Agency (FEMA) standards of 3-day minimum supply of emergency stores and equipment. Descriptive statistics and regression analysis were used to analyze data.
Results
One thousand one hundred and fifty surveys were returned and analyzed. Nine hundred and eight-three were sufficiently complete for logistic regression analysis with 394 responding “Yes” to having a 72-hour disaster kit (40.1%) while 589 had “No” as a response (59.9%).
Conclusion
The surveyed population is no more prepared than the general public, though surveyed beneficiaries overall are at an upper range of preparedness. Lower income and levels of education were associated with lack of preparedness, whereas training in disaster preparedness or having been affected by disasters increased the likelihood of being adequately prepared. Unlike results seen in the general public, those with chronic health care needs in the surveyed population were more, rather than less, likely to be prepared and those with minor children were less likely, rather than more likely, to be prepared. Duty status was assessed and only veterans were emphatically more probable than most to be prepared.

As attention to emergency preparedness becomes a critical element of health care facility operations planning, efforts to recognize and integrate the needs of vulnerable populations in a comprehensive manner have lagged. This not only results in decreased levels of equitable service, but also affects the functioning of the health care system in disasters. While this report emphasizes the United States context, the concepts and approaches apply beyond this setting.
Objective
This report: (1) describes a conceptual framework that provides a model for the inclusion of vulnerable populations into integrated health care and public health preparedness; and (2) applies this model to a pilot study.
Methods
The framework is derived from literature, hospital regulatory policy, and health care standards, laying out the communication and relational interfaces that must occur at the systems, organizational, and community levels for a successful multi-level health care systems response that is inclusive of diverse populations explicitly. The pilot study illustrates the application of key elements of the framework, using a four-pronged approach that incorporates both quantitative and qualitative methods for deriving information that can inform hospital and health facility preparedness planning.
Conclusions
The conceptual framework and model, applied to a pilot project, guide expanded work that ultimately can result in methodologically robust approaches to comprehensively incorporating vulnerable populations into the fabric of hospital disaster preparedness at levels from local to national, thus supporting best practices for a community resilience approach to disaster preparedness.

Evidence-based practice requires the use of data grounded in theory with clear conceptualization and reliable and valid measurement. Unfortunately, developing a knowledge base regarding children’s coping in the context of disasters, terrorism, and war has been hampered by a lack of theoretical consensus and a virtual absence of rigorous test construction, implementation, and evaluation. This report presents a comprehensive review of measurement tools assessing child and adolescent coping in the aftermath of mass trauma, with a particular emphasis on coping dimensions identified through factor analytic procedures. Coping measurement and issues related to the assessment of coping are reviewed. Concepts important in instrument development and psychometric features of coping measures used in disasters, terrorism, and war are presented. The relationships between coping dimensions and both youth characteristics and clinical outcomes also are presented. A discussion of the reviewed findings highlights the difficulty clinicians may experience when trying to integrate the inconsistencies in coping dimensions across studies. Incorporating the need for multiple informants and the difference between general and context-specific coping measures suggests the importance of a multilevel, theoretical conceptualization of coping and thus, the use of more advanced statistical measures. Attention also is given to issues deemed important for further exploration in child disaster coping research.

During mass-casualty incidents (MCIs), patient volume often overwhelms available Emergency Medical Services (EMS) personnel. First responders are expected to triage, treat, and transport patients in a timely fashion. If other responders could triage accurately, prehospital EMS resources could be focused more directly on patients that require immediate medical attention and transport.
Hypothesis
Triage accuracy, error patterns, and time to triage completion are similar between second-year primary care paramedic (PCP) and fire science (FS) students participating in a simulated MCI using the Sort, Assess, Life-saving interventions, Treatment/Transport (SALT) triage algorithm.
Methods
All students in the second-year PCP program and FS program at two separate community colleges were invited to participate in this study. Immediately following a 30-minute didactic session on SALT, participants were given a standardized briefing and asked to triage an eight-victim, mock MCI using SALT. The scenario consisted of a four-car motor vehicle collision with each victim portrayed by volunteer actors given appropriate moulage and symptom coaching for their pattern of injury. The total number and acuity of victims were unknown to participants prior to arrival to the mock scenario.
Results
Thirty-eight PCP and 29 FS students completed the simulation. Overall triage accuracy was 79.9% for PCP and 72.0% for FS (∆ 7.9%; 95% CI, 1.2-14.7) students. No significant difference was found between the groups regarding types of triage errors. Over-triage, under-triage, and critical errors occurred in 10.2%, 7.6%, and 2.3% of PCP triage assignments, respectively. Fire science students had a similar pattern with 15.2% over-triaged, 8.7% under-triaged, and 4.3% critical errors. The median [IQR] time to triage completion for PCPs and FSs were 142.1 [52.6] seconds and 159.0 [40.5] seconds, respectively (P=.19; Mann-Whitney Test).
Conclusions
Primary care paramedics performed MCI triage more accurately than FS students after brief SALT training, but no difference was found regarding types of error or time to triage completion. The clinical importance of this difference in triage accuracy likely is minimal, suggesting that fire services personnel could be considered for MCI triage depending on the availability of prehospital medical resources and appropriate training.

Children, with their specific vulnerabilities and needs, make up to more than 20% of society, so they are at risk of getting involved in disasters. Are the specialists treating them for medical problems in daily life also capable to deal with them in disaster situations?
Hypothesis/Problem
The goals of this study were to evaluate perceived knowledge and capability of tertiary pediatricians to deal with disasters, to identify promoting factors, and to evaluate education need and willingness to work.
Methods
A survey looking for demographics, hospital disaster planning, estimated risk and capability for disasters, training, and willingness to work, and a set of six content assessment questions to evaluate knowledge, were presented to emergency pediatricians and pediatric emergency physicians in specialized tertiary centers.
Results
The response rate was 51%. Thirty-five percent had disaster training and 53% felt that disaster education should be obligatory in their curriculum. Risk for disasters was estimated from 2.4/10 for nuclear incidents to 7.6/10 for major trauma. Self-estimated capability for these situations ranged from 1.8/10 in nuclear incidents to 7.6/10 in major trauma. Unconditional willingness to work ranged from 37% in nuclear situations to 68% in pandemics. Mean score on the questions was 2.06/6. Training, knowledge of antidote and personal protective equipment (PPE) use, self-estimated capability, and exposure were significant predictors for higher scores. Willingness to work correlated significantly with age, self-estimated capability, and risk estimation. In case of chemical and nuclear incidents, there was correlation with knowledge on the use of decontamination, PPE, and radio-detection devices.
Conclusion
Despite a clear perception of the risks and a high willingness to work, preparedness is limited. The major conclusion is that basics of disaster management should be included in pediatric training.

Influenza is a major concern for Emergency Medical Services (EMS); EMS workers’ (EMS-Ws) vaccination rates remain low despite promotion. Determinants of vaccination for seasonal influenza (SI) or pandemic influenza (PI) are unknown in this setting.
Hypothesis
The influence of the H1N1 pandemic on EMS-W vaccination rates, differences between SI and PI vaccination rates, and the vaccination determinants were investigated.
Methods
A survey was conducted in 2011 involving 65 Swiss EMS-Ws. Socio-professional data, self-declared SI/PI vaccination status, and motives for vaccine refusal or acceptation were collected.
Results
Response rate was 95%. The EMS-Ws were predominantly male (n=45; 73%), in good health (87%), with a mean age of 36 (SD=7.7) years. Seventy-four percent had more than six years of work experience. Self-declared vaccination rates were 40% for both SI and PI (PI+/SI+), 19% for PI only (PI+/SI-), 1.6% for SI only (PI-/SI+), and 39% were not vaccinated against either (PI-/SI-). Women’s vaccination rates specifically were lower in all categories but the difference was not statistically significant. During the previous three years, 92% of PI+/SI+ EMS-Ws received at least one SI vaccination; it was 8.3% in the case of PI-/SI- (P=.001) and 25% for PI+/SI- (P=.001). During the pandemic, SI vaccination rate increased from 26% during the preceding year to 42% (P=.001). Thirty percent of the PI+/SI+ EMS-Ws declared that they would not get vaccination next year, while this proportion was null for the PI-/SI- and PI+/SI- groups. Altruism and discomfort induced by the surgical mask required were the main motivations to get vaccinated against PI. Factors limiting PI or SI vaccination included the option to wear a mask, avoidance of medication, fear of adverse effects, and concerns about safety and effectiveness.
Conclusion
Average vaccination rate in this study’s EMS-Ws was below recommended values, particularly for women. Previous vaccination status was a significant determinant of PI and future vaccinations. The new mask policy seemed to play a dual role, and its net impact is probably limited. This population could be divided in three groups: favorable to all vaccinations; against all, even in a pandemic context; and ambivalent with a “pandemic effect.” These results suggest a consistent vaccination pattern, only altered by exceptional circumstances.

The worldwide use of rail transport has increased, and the train speeds are escalating. Concurrently, the number of train disasters has been amplified globally. Consequently, railway safety has become an important issue for the future. High-velocity crashes increase the risk for injuries and mortality; nevertheless, there are relatively few studies on high-speed train crashes and the influencing factors on travelers’ injuries occurring in the crash phase. The aim of this study was to investigate the fatal and non-fatal injuries and the main interacting factors that contributed to the injury process in the crash phase of the 2013 high-velocity train crash that occurred at Angrois, outside Santiago de Compostela, Spain.
Methods
Hospital records (n=157) of all the injured who were admitted to the six hospitals in the region were reviewed and compiled by descriptive statistics. The instant fatalities (n=63) were collected on site. Influencing crash factors were observed on the crash site, by carriage inspections, and by reviewing official reports concerning the approximated train speed.
Results
The main interacting factors that contributed in the injury process in the crash phase were, among other things, the train speed, the design of the concrete structure of the curve, the robustness of the carriage exterior, and the interior environment of the carriages. Of the 222 people on board (218 passengers and four crew), 99% (n=220) were fatally or non-fatally injured in the crash. Thirty-three percent (n=72) suffered fatal injuries, of which 88% (n=63) died at the crash site and 13% (n=9) at the hospital. Twenty-one percent (n=32) of those admitted to hospital suffered multi-trauma (ie, extensive, severe, and/or critical injuries). The head, face, and neck sustained 42% (n=123) of the injuries followed by the trunk (chest, abdomen, and pelvis; n=92; 32%). Fractures were the most frequent (n=200; 69%) injury.
Conclusion
A mass-casualty incident with an extensive amount of fatal, severe, and critical injuries is most probable with a high-velocity train; this presents prehospital challenges. This finding draws attention to the importance of more robust carriage exteriors and injury minimizing designs of both railway carriages and the surrounding environment to reduce injuries and fatalities in future high-speed crashes.
